Traffic from one site-to-site network to another site-to-site network

[Zulan]

Hello! I'm having trouble getting traffic to flow from one site-to-site network that is a co-location network to our Azure network also connected with a site-to-site ipsec tunnel. It works from all other branchoffices but from the co-location network. I'm not sure where to start troubleshooting this, might be even be on the azure side. Any ideas what to check?`

Can you be a little more specific? Can you provide more details of the problem?

I will try, I have been asked to help out with this network and actually know quite little about it. But there has been a site-to-site VPN to some Azure servers for quite some time. Traffic works perfectly from the main network and from all the branch offices to this azure network. Then a new a new co-location was needed. A new "Non-Meraki VPN Peer" was setup with availability set to "All networks" the same as Non-Meraki VPN tunnel configured to Azure. But pings from the co-location works to all networks except Azure.

Is this new Non-Meraki VPN Peer with Azure too? That wasn't clear. Anyway, you cannot route two Non-Meraki VPN Peers for them to communicate, if you want another non-Meraki peer to reach the Azure devices and vice versa, it is necessary to configure a tunnel directly with Azure.

No, the new VPN tunnel is not to azure. It's a local co-location provider. I actually had a hunch that was the answer. Thanks!
